Product Description
Features
- Wide range of voltage & contacts configuarations
- Electromechanical design
- Hand reset contacts
- Protective transparent cover for the element
- Compact panel mounting case
Application
High speed interface between the protection system and the circuit breaker Functions requiring a
number of simultaneous switching operations,interlocks in control and closing circuits
Principle of Operation
High speed tripping relays are voltage operated, attracted armature type with 5 contacts per
element. Each element is enclosed in a dust proof moulded,transparent, polycarbonate cover.
Radio metal is used for the magnetic components such as the armature, the core and the yoke of
the tripping relay to ensure good electrical performance.
The contacts are made of phosphor bronze and are nickel plated. The contact tips are made of pure silver. The use of these materials ensures very good contact performance.
